Abstract: 1501627 Rolling mill control DAVYLOEWY Ltd 2 April 1975 [1 April 1974] 14258/74 Heading B3M [Also in Division G3] A method of operating a tandem strip mill involves keeping constant the interstand tension in a strip S being rolled between a pair of stands, by adjusting the roll gap of either the upstream or downstream roll stand, and keeping the strip gauge constant by varying the roll speed of either the upstream or downstream stand. In one form, the strip gauge is measured at 7 and any error signals are used to control the speed of rolls 1 and 2 (or alternatively rolls 5 and 6). The strip tension is measured by determining the pressure acting on a pivoted roller 8, and any error signal is similarly used to adjust the roll gap of either roll pair. In place of the roller 8 a looper roller may be used, the position of the roller providing an indication of the strip tension.

Title: Improvements in metal plates adapted to be etched to form printing plates
IPC: B41N1/06
Filed: 1951-06-15
Abstract: 716,123. Printing-surfaces etching. WESTFALISCHE LEICHTMETALL-WERKE GES. June 15, 1951 [June 29, 1950], No. 14284/51. Class 100 (2) A metal plate adapted to be etched to form a printing plate has a surface consisting of an alloy of a predominant base metal with a second metal which is higher in the electro chemical series than the base metal. The design is etched with acid into the surface of the plate. The alloy coating may be formed by interfusing copper or silver and zinc, or silver and copper by electrolytic deposition. Undercutting during etching is avoided since the electrolytic potential decreases gradually with increasing depth of the metal owing to the interfusion of the second metal with the base metal. A copper, zinc plate may be interfused, annealed by heat treatment to produce a zinc-copper alloy and the etching subsequently carried out with a solution of nitric acid.

Fats and fatty oils, purifying.-A mill for refining crude sesame oil &c. by treatment with salt water comprises an annular trough or chamber, preferably of V-shaped cross-section, one or more rolls situated within the trough with their axes of rotation extending parallel or suhstantially parallel to the depth of the trough and of such shape as to conform in section along their axes of rotation substantially to the cross-section of the trough, means for rotating the rolls, and means for causing them while rotating to travel relatively to the trough or the trough relatively to the rolls. As shown, the annular trough 1 of V-shaped cross-section is supported on a hollow base 2 and contains two conical rolls 3 arranged vertically with their working faces in close proximity to the walls of the trough so that the crude material is squeezed as it passes between the rolls and the trough. The rolls, which are preferably provided with closely-spaced longitudinal grooves, are mounted upon vertical spindles 4 depending upon radial arms 5 mounted by means of a sleeve 7 upon a central stationary shaft 6 which extends down into the base 2. The sleeve 7 is keyed to a bevel-wheel 8 gearing with a wheel 9 on the horizontal driving-shaft 10. The rolls are geaned by wheels 14, 15 to a fixed wheel 13 on the shaft 6 so as to rotate on their own axes as they are carried round the trough. A bridge 16 carried on the upper part of the trough supports the rolls 3, arms 5, gearing 13. 14, 15, and shaft 10. Conical draw-off valves 18 at the bottom of the trough are mounted upon the arms 19 of a member 20 which can be raised or lowered upon the lower part of the shaft 6 by means of a screw-operated device 22. The oil is received in a conical tray 23 and passes by a conduit 24 to a strainer 26. A zinc box 27 encloses the epicyclic gearing and screens it from the oil, and a zinc hood 28 extends over the trough and is provided with inspection windows. In operation, the crude oil is placed in the trough and salt water added; the rolls are rotated until the oil becomes fairly clear, and then the speed of rotation of the rolls is reduced and the process continued until the oil is quite clear, when the machine is stopped and the valves 18 opened to deliver the oil. The space between the rolls and the sides of the trough may be tapered so as to decrease towards the top.

Title: Improvements relating to the treatment of aqueous liquids by electro-dialysis
Inventor: KRESSMAN THEODORE ROGER ERNEST
IPC: B01D61/48
Filed: 1958-05-07
Abstract: 882,601. Electro-dialysis of liquids. PERMUTIT CO. Ltd. April 29, 1959 [May 7, 1958], No. 14692/58. Class 41. In the electro-dialysis of liquids by treatment in compartments bounded by ion-selective membranes, a de-salting liquid of low salt content e.g. 1000 p.p.m. or less flows through compartments filled with ion-exchange material, and the concentrating fluid flowing through the intervening compartments is then divided and a part treated as desalting liquid, flows through unfilled compartments, and this salt-depleted stream returned to the first stage as the concentrating stream. The process may be applied to water used to cool cans of spent radio-active elements whereby salts e.g. Na 2 CO 3  are removed from the alkali liquor used in the cooling pond. The cells used for the concentrating liquid in the first stage may also be filled with ion-exchange material. Preferably a combination of anion and cation exchange materials are used e.g. sulphonated cross-linked polystyrene (cation resin) and chlor-methylated and aminated cross-linked polystyrene (anion resin) A pond 21, Fig. 6, used cool cans of spent radioactive materials, is connected by a pump 22 and filter 23 to the de-salting compartment of a multi-cell 24 having 120 anion selective and the same number of cation selective membranes composed of the above resins in bead form bonded by P.V.C. The end electrode compartments are fed independently with sodium sulphate solution. The pond water contains 200 p.p.m. of salts, and emerges from the cell containing 6 to 8 p.p.m., which is recycled to the pond after additions of caustic soda solution. The concentrating liquid containing sodium carbonate and some caustic soda at the rate of 1000 p.p.m. is fed as a desalting stream into a second cell 26, and part as concentrating stream which depletes the de-salting stream to 500 p.p.m. and this is recycled as concentrating stream to the first stage. Specifications 776,469 and 877,239 are referred to.

Title: An improved meat clamping means for slicing machines
IPC: B26D7/02
Filed: 1927-06-01
Abstract: 296,468. Coulson, E. June 1, 1927. Cutting slices in succession.- A meat clamp comprises a clamping-bar 1 pivoted at its midpoint 2 to a lever 3 pivoted to a bracket 5a on the feed table 5. The bracket 5a has a cam face 5b engaged by a revoluble cam 6 pivoted to a rod 7 connected to a trigger handle 8. A spring 9 abuts against a shoulder 3<b> on the lever 3 and a collar 7<a> on the rod 7, and normally presses the cam 6 against the face 5<b>. The upward pressure of the meat on the clamp tends to make the cam 6 grip the face 5b more tightly and the meat is thus securely held. The face 5b and the cam 6 may be roughened or serrated to increase the friction between them. The face 5b is cut away at 5<c> to receive the cam 6, the arm 3 being thus positively retained in its raised position.

Title: Power plant control systems
IPC: F02C9/56
Filed: 1975-04-10
Abstract: 1467949 Automatic control systems; load sharing GENERAL MOTORS CORP 10 April 1975 [17 July 1974] 14750/75 Heading G3R The fuel supplied to each of a plurality of gas turbines driving a common variable load, the rotors of a helicopter, is controlled in respect of (a) the difference between the measured power developed by the respective engine and the highest developed by any engine, and also (b) the difference between a desired load speed and the actual load speed. Thus, power is shared equally between the engines while they drive the load at a desired speed. The embodiment has three engines driving a single gear box coupled to two rotor blades. Each engine has an isochronous governor controlling its fuel valve,  whose setting is adjusted by electronically controlled servomotors in response to (a) pilot operated rotor pitch setting, (b) pilot operated load setting, throttle, (c) the load sharing control signal (d) an integrated speed error signal (e) power turbine inlet temperature reaching an upper limiting value. In addition, the control system is inhibited if the load speed is below 40% of rated value, and the speed control only is inhibited if the load speed is below 85% of rated. The speed is measured by inductive pick-ups, the frequency of whose signals is converted into a D.C. voltage. The load is measured as the product of speed and torque, the latter being measured by determining the phase angle between the signals from the speed inductive pick-up and from a reference pick-up. The load signals are supplied to a "select highest" logic element whose output is compared with the individual load signal to form a "load error" signal for each respective engine. When the speed control becomes effective at 85% rated speed a ramp signal is generated with which the desired speed is compared in a "select lowest" logic, whose output is compared with the actual speed; this limits the acceleration to a safe value, set by the slope of the ramp. For safety reasons many circuits and the speed pick-offs are dupli-  cated and fuel is cut-off in the event of overspeed. If this happens to one engine the system automatically shares the load between the remaining engines.

Title: Improvements relating to the manufacture of sheet metal pipes and the like
IPC: B21C37/08
Filed: 1928-05-21
Abstract: 311,946. Hume, W. R. May 21, 1928. Pipes.-The meeting edges of a curved sheet metal blank for use in the manufacture of a pipe or the like, which are normally flat, are bent slightly inwards as shown in Fig. 2, so that they may spring outwardly into the desired curvature upon release of the pressure. The blank is subsequently pressed against an abutment to bring the edges into contact where they are temporarily secured by tack welding &c. and finally transferred to an arc welding machine. The bending is effected progressively by a reciprocating die 22 having a concave surface with a V-shaped ridge 26 co-operating with a similar recess 81 in. a convex fixed internal die 28. The fixed die is secured by angle irons 33 to thin legs 32, Fig. 7, which pass through the open seam, are braced at 36 and are secured by arms 37 to a bearing 38 adjustable by a screw and hand wheel 43 fixed in adjusted position by a pin 44. The die 22 is secured to a ram 17 reciprocated in guides fixed to a braced framing 6, by an eccentric 16 on a shaft 9 provided with fast and loose pulleys. The cam has a removable cap 18 to facilitate assembly. The pipe rests in adjustable slotted cross bars 51 pivoted to a wheeled carriage 49 which is traversed intermittently on a channel girder 47 by hand or by rack 72 and pinion 71 driven by ratchet mechanism 68, 69 from a weighted lever 66. This lever is put into operation when the ram is raised, by a chain, rod or flexible link adjustably connected thereto and secured to a lever 64 operated by a cam 56 on the shaft 9 through a lever 58, rod 61 and lever 62. The shaped blank is then removed and placed in a channel member 83, Fig. 12, and its edges pressed together by the co-operation of flanges 74, 74<a> of this member with the horizontal flange 75 of an abutment 76. The abutment is adjusted by screws 78 and the flange 75 and part adjacent thereto are perforated at 98 to facilitate tack welding of the edges after pressing them together. The member 83 carries guide members 94 and is pressed upwards by fluid pressure plungers fed from a common supply 89. To ensure that the ends of the pipe are at right angles to the length of the blank, they engage respectively a stop 95 and a wedge driven in between the other end and an inclined stop 97.
